Object detection in 3D UWB subsurface images

The detection of plastic-cased antipersonnel landmines in 3-D high-resolution UWB radar images by means of thresholding in energy projected (EP) maps is considered. The improvement of the energy projection method - windowed energy projection (WEP) is introduced to diminish the quantity of false alarms caused by the high level of the clutter peculiar to the EP maps. The advantages of the technique are described by means of receiver operator curves (ROC). The ROC are built for the datasets acquired over the minefield simulation site under different environmental conditions.
